Having seen in the September Number of the Geological Magazine (p. 408), the Catalogue of Types of Fossil Fishes in the collection of my valued friend and fellow-worker Sir Philip de Malpas Grey Egerton, Bart,, M.P., with whom I have collected for so long a time, it occurred to me that the addition of the list of the type specimens of genera and species in my own collection would be a useful supplement to Sir Philip Egerton's carefully prepared catalogue, and might not be wholly unacceptable to the student in Palichthyology. I therefore beg to subjoin it, and, in doing so, to reecho the sentiment expressed by my friend, that my collection, like his own, although a private one, is always accessible to the student in Geology or Palæontology who may deem it of sufficient interest to visit Florence Court in order to study it.
